Cuno's line of 8000 series cartridges provide the continuing benefits of Cuno filtration in a user friendly design. A choice of medias such as graded density carbon and granular activated carbon with micron ratings from 0.5 to 5, as well as optional integrated scale inhibition (See CFS8112S) provide solutions to varying water conditions. The 8000 series cartridges do not require activation for functionality, allowing an operator to change cartridges in seconds.
